    (54) Curable silicone composition


    (57) A curable silicone composition comprising as a basic com­ponent an organopolysiloxane having at least two silicon-­bonded alkenyl groups, a silicon-bonded fluorine-­containing substituent of the formula (I):

    wherein m is an integer of from 1 to 4, and n is an in­teger of from 1 to 6, and /or the formula (II):

    wherein m and n are as defined above, and at least one silicon-bonded fluorine-containing substituent of the for­mula (III):
    ClF2l+1(CH₂)k-      (III)
    wherein k is an integer of from 1 to 4, and l is an in­teger of from 1 to 10, and/or the formula (IV):
    ClF2l+1-(-CH₂-)k-O-(-CH₂-)m-      (IV)
    wherein k, l and m are as defined above, and further com­prising an organohydrogenpolysiloxane, and a platinum fam­ily metal catalyst. This composition can form a coating film having a low surface energy and therefore having good release properties, etc.
